hello everyone.
i am having some issues but i want to check they are coding issues by me and not SDK issues..
fist i have a 2.0 i phone
using the toolchain as described for 1.2/2.0

i am getting a huge build issue

code follows:

// Set up the window and content view
CGRect screenRect = [[UIScreen mainScreen] bounds];
self.window = [[[UIWindow alloc] initWithFrame:screenRect] autorelease];

// Add the image as the background view
UIImageView *anImageView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
anImageView.image = [UIImage imageNamed:@"MyBackground.png"];
self.contentView = anImageView;
[anImageView release];
[self.window addSubview: self.contentView];

// Show the window
[self.window makeKeyAndVisible];

im getting errors for UIScreen and a few other is this because they are not supported or what?

There is no UIScreen in open tool chain
use this instead

Code:

CGRect screenRect =  [ UIHardware fullScreenApplicationContentRect ];

so the code would be

//new code
CGRect screenRect = [ UIHardware fullScreenApplicationContentRect ];
self.window = [[[UIWindow alloc] initWithFrame:screenRect] autorelease];

// Add the image as the background view
UIImageView *anImageView = [[UIImageView alloc] initWithFrame:[[UIHardware mainScreen] applicationFrame]];
anImageView.image = [UIImage imageNamed:@"MyBackground.png"];
self.contentView = anImageView;
[anImageView release];
[self.window addSubview: self.contentView];

// Show the window
[self.window makeKeyAndVisible];

correct?
